Question

Hasil dari 2(x-1)+3(2x+3)=15

Answer 1

2(x - 1) + 3(2x + 3) = 15
(2 × x) (2 × -1) + (3 × 2x) (3 × 3) = 15
2x - 2 + 6x + 9 = 15
2x + 6x - 2 + 9 = 15
8x + 7 = 15
8x = 15 - 7
8x = 8
x = 8/8
x = 1

Answer 2

2(x - 1) + 3(2x + 3) = 15
2(x) + 2(-1) + 3(2x) + 3(3) = 15
2x - 2 + 6x + 9 = 15
2x + 6x - 2 + 9 = 15
8x + 7 = 15
      8x = 15 - 7
      8x = 8
        x = 8/8
        x = 1
